I try on blank preset even the input is minimum, only connect on powercode and phone out. The noise happen same way.

I mean this knob

I use AIAIAI headphone it has no volume control on itself

Also noise came from only phone jack

In my case on Helix, If I turn the phone volume near 3oclock degree to maximum, I can listen the noise.

I did it with no connection on any devices, jack, amp blabla anything.

I turn off every fx inside the preset and make the input volume to 0db(It means I check it with no input).

However without all my effort, I still can listen the noise.

I check the headphones and connecting jacks but no problems are found.

Is it only happen to me or happen to every helix devices?
